One of our clients has just discovered a bug - which I confirmed, when zipping a number of folders/files.

Basically, I have tested zipping a number of folders (about 2MB each) together and saw that the total quota was not increased according to the size of the zip file, but when the zip file is deleted, the quota is decreased.

Since I have not upgraded yet, could you please confirm if this bug was fixed in 3.8.5?

When a folder is created and a file is uploaded to that folder, the quota increases as it should. If the folder is deleted together with its contents (contents not deleted first), the quota does not decrease to its actual value.

This quota update issue is a big issue for us due to space limitations in our server.
